Preserved communication abilities promote healthy ageing. To this end, the age-typical loss of sensory acuity might in part be compensated for by an individual's preserved attentional neural filtering. Is such a compensatory brain-behaviour link longitudinally stable? Can it predict individual change listening behaviour? We here show that behaviour and filtering ability follow largely independent developmental trajectories modelling electroencephalographic behavioural data N = 105 ageing individuals (39-82 y). First, despite expected decline hearing-threshold-derived acuity, listening-task performance proved stable over 2 y. Second, were correlated only within each separate measurement timepoint (T1, T2). Longitudinally, however, our results raise caution on attention-guided metrics as predictors behaviour: neither at T1 nor its 2-year could change, under combination strategies.
